Nvidia agx xavier pinmux configuration

hi ,
i am trying to enable sensor processing engine gpio in Agx xavier .but unable to find tegra19x-mb1-pinmux-p2888-0000-a04-p2822-0000-b01.cfg file in kernel source code and
pinmux.0x0c2f1800 = 0x00000003; # CONFIG BB0 output
pinmux.0x0c303040 = 0x0000c004; # can1_stb_pbb0
pinmux.0x0c303048 = 0x0000c044; # can1_en_pbb1

unable to find addresses in source code .
can anyone helpme how to find that and enable pinmux for SPE.

thanks.

Hello,
That file (tegra19x-mb1-pinmux-p2888-0000-a04-p2822-0000-b01.cfg) is not in kernel source package. It’s in BSP package.
For example, 32.5:
L4T Driver Package (BSP)

hi i found the file but after configuring path variable ,unable to build the the firmware .

t23x target_specific.mk error is coming.

Hello,
I’m not sure about your comment by ‘unable to build the the firmware.’
That file need not re-build. Just update the file and re-flash the device. New config should take effect.

Hello,
Have you ever followed the instructions in “rt-aux-cpu-demo-fsp/doc/gpio.md”?
There are several configurations to be updated.
And also, you can check the GPIO pin level. For example, when SPE firmware’s running, check whether the GPIO OUT toggles.
